Stationary steam engines, simple and compound; especially as adapted to electric lighting purposes . s the same at both ends of thecylinder and that it possesses the advantage, common to allengines having a positive motion valve-gear, of being unre-stricted in speed. Many of these engines are already in use driving electriclighting machinery. THE CUMMER ENGINE. ALL of the class of engines now under considerationhave been seen to differ radically from the enginespreviously described (as not well fitted for direct connec-tion to the dynamo), and to have a number of character-istic points in common which especially fit them for use indirect connection. This latter class of engines, however,exhibit some differences among themselves which are im-portant and very interesting to the engineer and the userof steam power. The engine last described will have been seen to differ,in a very notable way, from that which immediately pre-ceded it. The latter had a system of valves that differedfrom the former no less radically than did its system ofregulation. We have now to study an engine which re-.
